Chronic Kidney Disease (CKD) is called the “silent disease” because most people lose up to 90% of kidney function before feeling seriously unwell. At the Nephrology Department, Ruby Hall Clinic Hinjawadi, patients often arrive saying they had no symptoms — yet their kidneys were already badly damaged. Recognising the early warning signs can be life-changing.
10 Early Warning Signs of Kidney Disease
1. Swelling in the Feet, Ankles or Face
Failing kidneys cannot remove excess fluid, which builds up in tissues. Puffiness around ankles, feet, or face that does not resolve with rest is a key red flag.
2. Changes in Urination
Watch for: more frequent urination especially at night, less urine than usual, foamy or bubbly urine (protein leakage), or blood-tinged urine. Foamy urine is one of the earliest measurable signs of kidney damage.
3. Persistent Fatigue
Damaged kidneys produce less erythropoietin (EPO), causing anaemia. Fewer red blood cells mean less oxygen reaching muscles and brain — leaving you chronically exhausted despite adequate sleep.
4. Difficult-to-Control High Blood Pressure
Kidney damage raises blood pressure, and high blood pressure further damages kidneys. If you are on multiple BP medications but readings remain uncontrolled, get your creatinine and eGFR checked immediately.
5. Shortness of Breath
Retained fluid can accumulate in the lungs, causing breathlessness especially when lying flat. Anaemia also reduces oxygen-carrying capacity.
6. Back or Flank Pain
A dull ache beneath the ribcage can indicate kidney stones, infections, or polycystic kidney disease (PKD). A urine test and ultrasound can clarify the cause quickly.
7. Nausea and Loss of Appetite
Waste products accumulating in the blood (uraemia) cause persistent nausea, vomiting, metallic taste, and unintentional weight loss. These are signs of advancing disease.
8. Skin Itching and Dryness
Excess phosphorus from failing kidneys deposits in skin, causing intense itching that does not respond to antihistamines. Yellowing and extreme dryness can also develop.
9. Muscle Cramps and Restless Legs
Electrolyte imbalances from kidney disease cause painful leg cramps at night and restless leg syndrome — commonly overlooked kidney symptoms.
10. Brain Fog and Dizziness
Anaemia and toxin buildup affect brain function, causing poor concentration, memory lapses, and light-headedness. Often dismissed as stress but may be an early kidney warning sign.
Who Is at High Risk?
Get annual kidney checks if you have: diabetes, high blood pressure, a family history of kidney disease, recurrent kidney stones, obesity, age over 60, or regular use of painkillers (NSAIDs like ibuprofen).
Three Tests That Detect CKD Early
- Serum Creatinine & eGFR — eGFR below 60 for 3+ months confirms CKD
- Urine Albumin-to-Creatinine Ratio (UACR) — detects protein leakage, the earliest kidney damage marker
- Renal Ultrasound — checks kidney size, structure, stones, and cysts
All three are available on the same day at Ruby Hall Clinic Hinjawadi.
Frequently Asked Questions
Can kidney disease be reversed?
Acute kidney injury (AKI) from dehydration or medications can fully recover with prompt treatment. CKD cannot be reversed, but progression can be significantly slowed with proper management of blood pressure, blood sugar, and diet.
When should I see a nephrologist?
See a nephrologist if: your creatinine is elevated, eGFR is below 60, you have protein or blood in urine, blood pressure is resistant to treatment, or you have diabetes or hypertension with any kidney symptom.
